WebHá 2 dias · The findings rest on the widely held theory that Earth’s atmosphere was formed by gases released from volcanic activity on its surface. Today, as during the earliest days of the Earth, magma flowing from deep in the Earth contains dissolved gases. When that magma nears the surface, those gases are released into the surrounding air. WebThere seem to be two types of atmospheres: original ones, formed from gas present in the primordial dust cloud, and evolved or outgassed ones, whose gases have gradually come out of the interior of the planet, probably as the result of volcanism. The atmospheres of the gas giant planets are largely original. ipower 600 watt hps mh
